The school offers an academic program for boys in transitional kindergarten (preschool) through eighth grade, as well as military structure and leadership training.

St. Catherine’s Academy was founded by Mother Maria Pia Backes, O.P., one of the three foundresses of the Dominican Sisters of Mission San Jose.

Despite suffering a major earthquake in 1933, a statue of St. Joseph remained standing and it currently resides in the indoor pool area today.

St. Catherine’s Academy has an 8-acre (3.2 ha) campus in Anaheim, California, approximately two miles (3 km) from Disneyland.

Decorated by the artist Jan Henryk de Rosen and equipped with a full-size organ, it is dedicated to the memory of Captain William Maguire, the cadets' chaplain in the 1950s.

St. Catherine’s competes in the Parochial Athletic League (PAL) in three sports: flag football, volleyball and basketball.
